When performing slope operations maintain heading +/- __degreses, drift +/- __foot until touchdown and then ________ allowed.
CAUTION 1: The __________ can be easily _________during takeoff and landing if excessive cyclic movements occur. A thorough _________ must be performed prior to flight which includes crew coordination to ________mast moment limits.
CAUTION 2: If the successful completion of the landing is in doubt at _________ or it appears that a ______may be exceeded, ________the maneuver and return to a hover.
When performing slope operations maintain heading +/- 5 degreses, drift +/- 1 foot until touchdown and then no drift allowed.
CAUTION 1: The mast moment can be easily exceeded during takeoff and landing if excessive cyclic movements occur. A thorough crew briefing must be performed prior to flight which includes crew coordination to monitor mast moment limits.
CAUTION 2: If the successful completion of the landing is in doubt at any time or it appears that a limit may be exceeded, abort the maneuver and return to a hover.
The following Notes pertain to slope operations:
a. Note: Before performing slope operations, it is important to understand ____________ characteristics.
b. Note: Gound oscillations in _____ axis may be encountered. Pressing the ____ switch should damp out these oscillations.
c. Note: Crewmembers must be aware of the helicopter´s _______hovering attitude prior to landing.
d. Note: To improve the ____control at a hover the ________ function can be switched off IAW RFM. In this case ________ only as active…
The following Notes pertain to slope operations:
a. Note: Before performing slope operations, it is important to understand dynamic rollover characteristics.
b. Note: Gound oscillations in roll axis may be encountered. Pressing the FTR switch should damp out these oscillations.
c. Note: Crewmembers must be aware of the helicopter´s normal hovering attitude prior to landing.
d. Note: To improve the YAW control at a hover the YAW trim function can be switched off IAW RFM. In this case YAW SAS only as active…
Note: ____________ component is advantageous during approach and landing. The P* should consider selecting an area where a shallow approach can be accomplished with a___________
Note: Left crosswind component is advantageous during approach and landing. The P* should consider selecting an area where a shallow approach can be accomplished with a left crosswind.
During a fixed pedal setting approach adjust airspeed to ___knots or above until final. Upon establishing ___KIAS while maintaining less than ___FPM rate of descent, if the nose is ____of the ground track, ____the approach, if the nose is ___then ______approach. Arrive over the ______ of the landing area approximately_____ AGL __________. If the nose is to the left maintain altitude with the collective while _______forward speed until the aircraft is ______with the landing area. If the nose yaws to the right past the centerline apply _____. Collective application will accelerate the right yaw. When the aircraft is aligned with the intended landing direction and a _________ can be accomplished the IP will announce the_______________________.
During a fixed pedal setting approach adjust airspeed to 70 knots or above until final. Upon establishing 40 KIAS while maintaining less than 300 FPM rate of descent, if the nose is right of the ground track, abort the approach, if the nose is left then continue approach. Arrive over the first one-third of the landing area approximately 5 feet AGL at or above ETL. If the nose is to the left maintain altitude with the collective while decreasing forward speed until the aircraft is aligned with the landing area. If the nose yaws to the right past the centerline apply forward cyclic. Collective application will accelerate the right yaw. When the aircraft is aligned with the intended landing direction and a successful landing can be accomplished the IP will announce the maneuver is complete and restore the (A. Trim) YAW switch.

7. Autorotation - ___________
- As it pertains to performing the above T/R Drive Failure procedure:
a. The procedure will vary depending on the flight conditions, __________ and _______of the helicopter
